A truss is a strong frame of beams or bars that supports a roof, bridge, or other structure. Engineers use trusses because they are light but strong.

A truss is more specific than a frame or support. In buildings, it often means a triangular structure that carries weight efficiently. As a verb, it is more formal than just tie, and it is often used for food or medical support.
